The chemical recycling of CO2 is near the top of the agenda for chemists (Centi & Perathoner, 2009). The Sabatier reaction, for example, is useful in catalytically transferring carbon dioxide into a carrier of chemical energy (Muller et al., 2013). Methane thus produced has immense chemical value and can be converted into methanol (Cui et al., 2018) or ammonia (Bai et al., 2018). Methane thereby holds a feedstock potential for the synthesis of organic chemicals and can also be fed into the existing natural gas network:
CVD diamond: a review on options and reality
Published in Functional Diamond, 2023
The electric power to grow man made diamond can be selected from a manifold of options—including renewable sources. Methane (CH4) and hydrogen (H2), both key ingredients to grow CVD diamond, is mostly ordered from companies which may use natural gas for methane production. Methane is the primary component (90%) of natural gas that is not only an important energy source but also a valuable feedstock for the chemical industry. Methane, if burned, forms CO2, but CO2 can also be used the product methane in a back conversion process (“Sabatier process”). It is a catalytic driven conversion of carbon dioxide (CO2) into methane and well known 1897 [56]. The Sabatier reaction is attracting much attention, because it provides a recycling recipe of CO2 back into fuel. Green hydrogen is also required to grow diamond, which can be generated electrochemically by water splitting using “green electric power”. H2 together with CO2 forms methane, thereby removing CO2 from our atmosphere:
Spent Nuclear Fuel Incineration by Fusion-Driven Liquid Transmutator Operated in Real Time by Laser

We may adopt a non-alkaline coolant such as dry to avoid corrosion. An added advantage of using is conversion according —i.e., the Sabatier reaction61—into methane in the presence of catalysts (such as nickel or aluminum oxide) and 400°C and pressure. The other energy-intensive reaction example is the Haber-Bosch process of ammonia creation.62 The paradigm may be built on the heat exchanger pipe shown in Fig. 3; the coolant is delivered into the transmutator via the pipe and is heated.
